The move follows an advisory letter issued a week ago by the state Attorney General's Office recommending that community colleges tighten their admissions standards to be more in line with federal laws.

“We asked the Attorney General’s Office for clarification of our present policy and will abide by their advice,” Community College System President R. Scott Ralls said in a statement. “Until we receive further clarification, we will no longer admit individuals classified as illegal or undocumented immigrants into curriculum degree programs.”

The system last fall began admitting any illegal immigrant who was at least 18 years old and a high school graduate. Gov. Mike Easley said last week that he supported that policy, noting federal law doesn't clearly outline when illegal immigrants can attend community college.

A spokesman for U.S. Immigration and Customs Enforcement also said last week federal law didn't preclude colleges from admitting illegal immigrants.

The Attorney General's Office has agreed to ask federal officials to clarify rules regarding illegal immigrants and college enrollment.
